Description: the Hydraulic Internal Cutters are simple, efficient tools for cutting tubing, casing or drill pipe. They are available in sizes for cutting 1-1/2" tubing up to 20-1/2" casing.
MDX Collar Finders (not shown), assembled at the bottom of a Cutter, enable the operator to locate the nearest collar to the cutting depth. Construction permits free lowering into pipe. When the assembly is raised, the upper ends of the Collar Locators engage the space between two joints of pipe. Additional upward pull snaps the Shear Pin; the reaction in the string is very apparent at the surface and the operator then knows the exact location of the collar.
Features: Manufactured to exacting standards, Internal Cutters permit the redressing of a basic assembly in order to cut alternate sizes of pipe. Internal Cutters are used to cut tubing, casing or drill pipe. They may be run on sucker rods, macaroni strings, tubing, or drill pipe, depending upon the diameter of the pipe to be cut.
The MDX Internal Cutter consists of a Wiper Block (or a Drag Spring) Assembly to accomplish setting in the pipe; Slips and Cone Assembly to anchor the tool; a Main Spring to assist in maintaining uniform feed to the Knives; wedge-like Knife Blocks to drive the Knives upward and outward to engage the pipe; and hardened and ground Knives for easy, efficient cutting.
An important feature of the Bowen Internal Cutter is the "Automatic Bottom." This device permits the operator to set the cutter at any desired depth, to release the tool and to reset at another depth, all without coming out of the hole.
